    New Heatermeter Build - power and voltage issues.

    You note the new HM is not attached to the rPi.... did you initially connect the new HM to the rPi so the firmware could be loaded on the ATMEGA? If not then your HM is a blank slate, no operating system... Need to program the SD card and connect the rPi to the HM and let if boot and flash the...

    Pit Reading 400°F + when plugged in. K-Thermocouple

    Tell your son to pick up on this thread, with some patience and help from forum members he will get it working.... I still think the HM is gonna be superior to any other BBQ controller out there if you build a damper, to my knowledge no other controller has implemented a damper system, though I...

    Why can't this thing just work... (frustrated)

    Michel, I understand your frustration. In a situation like this I take the "shotgun" approach. Remove the rPi, pull the ATMEGA, then with a clean soldering iron QUICKLY reflow the solder on the entire board. If you soldered heavily the first time then a reheat to reflow is probably all you...

    Airburner - HeaterMeter Success!

    My first experience with the HM was with a generic bullet smoker... I was finding the pit would overshoot the target temp and hang there, the HM was helpless to control it because servo dampers hadn't been implemented yet. So the HM would monitor the pit just waiting for it to cool down so it...

    Thermal Couple Vs Thermal Probes (thermistors)

    If we were talking about meat probes being off 3-5 degrees in 100-200F range that may be something to be concerned about, 'cause you're relying on that temp to estimate doneness.... but the pit temp being off a couple degrees is not a big deal from my point of view. The pit temp varies quite a...

    Take a peek at my rain resistant box.

    I too wondered about the air intake for the box? I used to have a rig kinda like that for my HM alone, I found myself leaving the cover off so I could see and adjust the HM easier... Murphy's law eventually kicked in and the box filled with rain! LOL I have left my RD3 out on my grill 24/7...

    Thermocouple Noise When Using 2.4G Wifi

    Can you make the HM delay posting TC temp data until a few seconds after it goes from OFF to connected? This would keep the wonky part of the TC startup off the graph, I don't think anyone has a real need to see the TC temperature instantaneously after it is plugged in? I would accept the...

    Thermocouple Noise When Using 2.4G Wifi

    Why don't you try an off board thermocouple amp that you can shield better and move further away? This way you can get a better idea if this is caused by waves in the air or something coming through the circuits...

    Stable firmware release v15

    Magically, the missing probe reappeared today without doing anything... IDK WTH....

    Stable firmware release v15

    I dont recall installing any browser plugins recently, however, when I load chrome in incognito mode it does show all 3 probes... so I guess that indicates it is a browser plugin issue. I will look into that when I have time and report back when I find the culprit. Thank you for your help...

    Stable firmware release v15

    I also noticed when I load the noise graph the pit probe is missing (It does show in Firefox)

    Stable firmware release v15

    I did delete the user css section and reboot, probe1 was still missing so I figured that wasn't the problem. It's just odd that it is only chrome, firefox and MS Edge show all three probes. I've cleared the cache in chrome and tried every refresh keystroke I am aware to no avail.... Chrome is...

    Stable firmware release v15

    No, I mean the whole segment where the probe1 temp should be is missing (in Chrome),,,,

    Stable firmware release v15

    I have some odd behavior with my HM today, I did update to the latest release version but am not sure if it is related to this issue. In Chrome the temperature display (above the graph) does not show Probe1, I only see two sections which display probe 2 and 3 (in addition to the Pit Probe...

    Reverse Voltage fried my HeaterMeter

    I've fixed one HM that was hit with reverse polarity, I believe the inductor in the blower feedback circuit was one of the things that fried. After reverse polarity was applied (and the smell of heat/burn detected and power quickly removed), I applied proper polarity power and the HM seemed to...
